Hi @JingsongLi, I completely agree with your assessment! The test failures and bugs you just mentioned are exactly why I realized the current PR implementation (using async refreshes and the HASH index) is fundamentally flawed and should not be merged. That is why my previous message was proposing a completely new design to replace this PR. The new plan (tracking live keys entirely in memory via RowKind insert/deletes) completely eliminates async refreshes, disk scans, and HASH index dependencies. By removing those mechanics, it naturally prevents the double-counting and vanished-bucket issues you ran into during regression testing. I haven't written the code for this new design yet. Could you take a look at the conceptual plan in my previous comment? I'd love to get your thoughts on that new direction before I start implementing it -- This is an automated message from the Apache Git Service.
